It is known that modular buildings are sectional prefabricated structures that consist of multiple sections called modules. The modules can include any number of walls, floors, ceilings, and roof components. The modular building is often prefabricated, such as in a six sided boxes constructed in a remote facility, then delivered to their intended site of use. Additionally, the modules can be placed side-by-side, end-to-end, or stacked, allowing a wide variety of configurations and styles in the building layout.
The inventor was aware that modular buildings were not always efficient to build or transport. Nor did these modular building have enough flexibility to form a wide variety of buildings. Nor were the aesthetics of the finished structures satisfactory for most consumers in the market. And the inventor realized that the individual components for the modular buildings were not perfect, often too heavy or bulky. The inventor also knew that the finished modular buildings were often flimsy, unable to withstand strong winds or earthquake type forces.
Through research and interaction with construction workers and contractors, the inventor learned that the construction of buildings and various structures for recreational or utility purposes traditionally requires the person building the structure to have at least moderate carpentry and construction skills. In addition, tools and materials such as hammers, nails, screws and screwdrivers, and saws are required. Depending on the size and scale of the project, it also can be necessary to dig holes or trenches for a foundation, mix and pour cement for that foundation. Then, upon completion of the task, the person must remove the resultant spoils and unused construction materials. All of these require significant physical effort, are time-consuming, and of significant expense.
The inventor decided to invent a modular system of buildings that utilized lightweight, yet structurally sound modular components that interconnected through frictional forces, so that a direct lateral force could mate two components together, and thus, the need for special tools and skillsets could be minimized. The inventor knew that the frictional engagement should also provide sufficient flexibility to withstand external forces playing on the panels and seams of the modular structure. The inventor also figured out that if the time in which to construct the structure could be reduced, the labor costs could also commensurately be reduced.
Through research, the inventor realized that the system should include all of the required structural components including floors, walls, ceilings, trusses, and roof elements. All of these components should be adapted to frictionally interconnect to each other. The inventor initially designed a foundation base with frictional channels that could form a supportive foundation for wall panels and floor panels through a frictional snap-lock engagement. The inventor realized that this kind of laterally direct engagement between modular components negated the need to slide the panels against the base, and thus require more space. The lateral connection reduced the need for this extra space.
Through trial and error, the inventor learned that adding projections and identically shaped recessions along the edges of the panels, and performing a frictional snap-lock engagement between them, additional structural integrity was created during the frictional interconnections. The inventor developed a double spike shape and a semicircle shape, making the peripheral edges of each shape interconnect through a frictional snap-lock engagement. These unique shapes helped the interconnections become stronger, yet still allowed for flexibility to withstand external forces.
The inventor did realize this aspect, and the modular building was suddenly more efficient. However, the inventor realized that the components were not diverse enough to build the different types and sizes of structures that the markets demanded. So the inventor continued diversifying the shapes and dimensions of the panels, adding a curved panel, an apex panel, an L-shaped panel, a T-shaped panel, and panels that created hexagonal shaped structures. The capacity to include lighting, staircases, and shingles was also integrated into the modular system so that the system could be used both indoors and outdoors.
Systems and methods for constructing modular buildings have been used for building quickly and efficiently in the past, yet none with the present characteristics of the present invention. See Patent numbers: U.S. 20120247043; U.S. 20130086850; U.S. Pat. No. 8,065,846 and U.S. Pat. No. 3,455,075.
For the foregoing reasons, there is a need for a system and method for constructing modular structures through a frictional snap-lock interconnection that minimizes the need for tools and sliding the components against each other.
The present invention is directed to a modular construction system that forms flexible structures that maintain structural integrity through lateral frictional snap-lock interconnections between individual building components without requiring the components to slide against each other, or necessitating the need for special tools for fastening. In some embodiments, the modular system may utilizes frictional channels that create a frictional snap-lock engagement to connect the modular components, and thus form the finished structure. The frictional channel connections use a direct lateral engagement to mate and hold components together. In this manner, an assortment of simple modular components can be interconnected without requiring extra space to slide the individual components against each other to interconnect.
The system comprises eclectic shapes and dimensions of modular building components, including, without limitation, a series of panels, bases, dividers, roof trusses, roof bases, and holes that can be configured into numerous structural designs. The components are connected in a particular configuration which permits multiple modular components to be mounted together in horizontal and vertical arrays. Each component may have a frictional channel that mates with a corresponding frictional channel from another component. The frictional channels are pre-cut in the components to allow for efficient mating through the frictional snap-lock engagement, or for connectors to seat in the frictional channels of adjacent members forming a clean joint between two channeled components.
In some embodiments, the modular system can also utilize fasteners, such as screws and bolts, to reinforce the frictional connections. Assembly in this fashion provides a friction fit and achieves substantial stability. This stability is present in completed and partially assembled structures, allowing whole projects or sections thereof to be moved during construction with minimal risk of structural collapse. However, the panels don't allow the fastener to pass all the way through. The thread that accepts the screw is made in the same panel.
Additionally, conduits may extend through the length of the panels, bases, dividers, roof trusses, roof bases, and holes, and conduits to enable passage of wiring, water lines, gas lines, and other habitual necessities. In some embodiments, the system supports the possibilities of a wide variety of configurations and specialty members, which may be added to effect distinct characteristics, features, and functionality.
The modular system for constructing a structure through frictional mating comprises: a base defined by a pair of channel sides and a pair of tongue sides. The base is generally elongated and has a substantially rectangular cross section. Each channel side on the base has two base protrusions that extend along the length of the base. The base protrusions provide surface area for support and rigidity. A base frictional channel forms between the two base protrusions. The base frictional channel is sized and dimensioned to generate friction when a panel is engaged within. The two base protrusions include a plurality of base apertures that form a transverse axis across the two base apertures. The base apertures enable passage of fasteners for providing additional structural integrity. Additionally, each tongue side defined by a tongue that extends along the length of the base. The tongue forms a supportive surface for holding up panels.
The system further comprises a wall panel defined by a plurality of wall panel edges. The wall panel edges are arranged to mate with the frictional channel in a frictional snap-lock engagement. At least one of the wall panel edges is defined by at least one wall projection that extends laterally. An example of the at least one wall projection can be a double-spike shape. At least one of the wall panel edges is also defined by at least one wall recession that recesses laterally. An example of the at least one wall recession can be a recessed double-spike shape that is identically shaped to the double-spike to create a corresponding mating surface. In this manner, the at least one wall projection is arranged to mate with the at least one wall recession of an adjacent wall panel in a frictional snap-lock engagement. Additionally, the wall panel is defined by at least one wall conduit used to carry wiring, water pipes, or gas lines.
The system further comprises a floor panel that provides a flat walking and/or supporting surface. The floor panel is defined by a plurality of floor panel edges. The floor panel edges are arranged to engage a junction that forms between the tongue and each protrusion. At least one of the floor panel edges is defined by at least one floor projection that extends laterally. An example of the at least one floor projection can be a semicircle shape. At least one of the floor panel edges is also defined by at least one floor recession that recesses laterally into the floor panel. An example of the at least one floor recession can be a recessed semicircle shape that is identically shaped to the semicircle shape to create a corresponding mating surface. In this manner, the at least one floor projection is arranged to mate with the at least one floor recession of an adjacent floor panel in a frictional snap-lock engagement. Additionally, the floor panel is defined by at least one floor conduit used to carry wiring, water pipes, or gas lines.
The system further comprises a divider that separates upper and lower floors in the structure. The divider is defined by a divider first side having a first frictional channel and a divider second side having a second frictional channel. The divider first side and the divider second side are arranged to support the plurality of floor panels. In this manner, a floor panel can rest on the first side, above the divider. Another floor panel can rest on the second side, below the divider. A first and second floor to a structure is thus formed. The first frictional channel and the second frictional channel are arranged to mate with the plurality of wall panel edges in a frictional snap-lock engagement. In this manner, a wall panel mates with the first frictional channel from above the divider, and another wall panel mates with the second frictional channel from beneath the divider. The wall panel and the floor panel meet in a substantially perpendicular orientation at the divider.
The system further comprises a roof truss defined by a generally arc shape. The arc shape of the roof truss helps carry off debris, such as rain and snow from the apex of the structure. The roof truss is further defined by a pair of lateral ends. Each lateral end has a roof frictional channel that is sized and dimensioned to create the frictional snap-lock engagement with other components, such as panels. The roof truss also has a plurality of roof apertures extending along the edges of the pair of lateral ends. The roof apertures enable passage of fasteners for securing panels to the roof truss.
The system further comprises a roof panel arranged to mate with the roof frictional channel in a frictional snap-lock engagement. The roof panel is defined by a plurality of roof panel edges. The roof panel frictionally attaches to the roof frictional channel from one edge, and rests on a roof base from an opposite edge. The roof base is defined by a generally rectangular block that provides structural integrity. A roof base frictional channel rests adjacently to the roof base. The roof base frictional channel mates with the roof panel in a frictional snap-lock engagement.
One objective of the present invention is to construct a structure with a minimal amount of tools and fasteners.
Another objective is to leverage the structural integrity of the structure with compressive forces and frictional snap-lock engagement, such that panels, dividers, trusses, and bases form a solid construction.
Another objective is to create sufficient flexibility between the frictional connections in the panels, dividers, and bases, such that the structure dampens vibrations caused by an earthquake and can withstand strong winds, tidal waves, and explosive reverberations.
Another objective is to provide a panel that connects to an adjacent panel without requiring one panel to slide across the edge of another. Rather the panels can mate directly into a frictional snap-lock engagement. This eliminates the need for extra space above and below the panels for sliding together.
Another objective is to provide flexibility of design to carry wires, water pipes, and gas lines through the panels, dividers, bases, and roof trusses.
Another objective is to enable the entire structure to be disassembled and moved without the use of heavy equipment.
Another objective is to enable easy storage of the individual pieces during disassembly of the structure.
Yet another objective is to provide expandability in order to incorporate new components and create large projects.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and drawings where:

The components may be prefabricated at a factory and assembled at the construction site.
In some embodiments, the modular system 100 can also utilize a fastener 126, such as screws and bolts, to reinforce the frictional interconnections. Assembly in this fashion provides a friction fit and achieves substantial stability. This stability is present in completed and partially assembled structures, allowing whole projects or sections thereof to be moved during construction with minimal risk of structural collapse. In some embodiments, the component interconnections have sufficient flexibility at their frictional connections, so that the structure dampens vibrations from earthquakes and can withstand external forces, such as strong winds, tidal waves, and explosive reverberations.
Additionally, conduits 196, 218 may extend through the length of the panels 165, 126, base 101, divider 109, roof truss 152, roof base 164, a hole 180 for plumbing fixtures, and conduits 196 to enable passage of wiring 148, water lines 150, gas lines, and other habitual necessities. In some embodiments, the system 100 supports the possibilities of a wide variety of configurations and specialty members, which may be added to effect distinct characteristics, features, and functionality. These may include, without limitation, lighting, roof shingles, stair cases, doors, and windows that incorporate into the finished structure.
Turning now to
A plurality of angles 102a, 102b, 103a, 103b form between the base protrusions 105a, 105b, 107a, 107b and the tongues 110a, 110b. At least one base frictional channel 104a, 104b forms between the base protrusions 105a, 105b, 107a, 107b. The base frictional channel 104a is sized and dimensioned to generate friction when a wall or floor panel 165, 126 is engaged within. In one embodiment, the base frictional channel 104a may have a width between ¼″ to 2″.
The base protrusions 105a, 105b, 107a, 107b include a plurality of base apertures 116 that form a transverse axis across the base 101. The base apertures 116 enable passage of the fastener 126 for providing additional structural integrity. The base apertures 116 from each protrusion 105a, 105b align to enable a straight passage for the fasteners 126. Additionally, each tongue side 110a, 110b is defined by a tongue 106a, 106b that extends along the length of the base 101. The tongue 106a, 106b forms a supportive surface for holding up the panels 165, 126. In one embodiment, the tongue 106a, 106b forms a substantially 90° with the base 101. In another embodiment, the tongue 106a, 106b may extend about 6″ from the tongue side 110a. Though a longer or shorter tongue 106a, 106b may be used.
The system 100 further comprises a wall panel 165 defined by a plurality of wall panel edges 141. The wall panel 165 is a vertical structural support means, which may be a continuous closed structure covering one-half of the long sides of the other panels 126, 160, or the wall panel 165 may be an open framework which provides access openings, such as a window or door. In some embodiments, the wall panel 165 comprises of half-wall panels joined together at a panel seam 146. The panel seam 146 is formed through a frictional snap-lock engagement. The panel seam 146 creates greater modular functionality by enabling the wall panel 165 to be bifurcated into two separate half-wall panels when a thinner wall panel is required during construction.
In some embodiments, the wall panel edges 141 are arranged to mate with the base frictional channel 104a in a frictional snap-lock engagement. At least one of the wall panel edges 141 is defined by at least one wall projection 122 that extends laterally from the wall panel edges 141. An example of the at least one wall projection 122 can be a double-spike shape. Though any shape may be used for the wall projection 122. At least one of the wall panel edges 141 is also defined by at least one wall recession 124 that recesses laterally and forms an identical shape to the wall projection 122. Both the wall projection 122 and wall recession 124 have a frictional periphery to form the frictional snap-lock engagement with each other.
The shape of the wall projection 122 is adapted to fit into the identical shape of the wall recession 124 of an adjacent wall panel 165. Consequently, the wall panels 165 may be interconnected together in by inserting a projections 122 of one wall panel 165 into a wall recession 124 of an adjacent wall panel 165. In addition, a fastening means may be used to further secure the wall panels 165 together. An example of the at least one wall recession 124 can be a recessed double-spike shape that is identically shaped to the double-spike to create a corresponding mating surface. In this manner, the at least one wall projection 122 is arranged to mate with the at least one wall recession 124 of an adjacent wall panel 165 in a frictional snap-lock engagement.
The direct engagement between the wall projection 122 and the wall recession 124 enable adjacent wall panels 165 to interconnect without requiring one wall panel 165 to slide across the edge of another wall panel 165. Rather the panels 165 can mate directly into a frictional snap-lock engagement. This eliminates the need for extra space above and below the panels 165 for sliding together. Additionally, the wall panel 165 is defined by at least one wall conduit 218 used to carry wiring, water pipes, or gas lines. The wall conduit 218 may extend laterally through the wall panel 165.
The system 100 further comprises a floor panel 126 defined by a plurality of floor panel edges 128. The floor panel 126 has the dual purpose of serving as a floor and a ceiling, depending on the relative position to the other components. The floor panel edges 128 are arranged to form the angles 102a, 102b, 103a, 103b between the tongue 106a, 106b and each protrusion 105a, 105b, 107a, 107b. In this manner, the floor panel 126 receives a supportive platform from above, or below, depending on the level of the floor panel 126.
At least one of the floor panel edges 128 is defined by at least one floor projection 130 that extends laterally from at least one of the floor panel edges 128. An example of the floor projection 130 can be a semicircle shape. At least one of the floor panel edges 128 is also defined by at least one floor recession 132 that recesses laterally into the floor panel 126. An example of the at least one floor recession 132 can be a recessed semicircle shape that is identically-shaped to a projecting semicircle shape to create a corresponding mating surface. Both the floor projection 130 and floor recession 132 utilize frictional connections along their floor panel edges 128 to form the frictional snap-lock engagement.
As illustrated in
In some embodiments, the floor panel 126 is comprised of half-panels joined together at the panel seam 146. The panel seam 146 is formed through a frictional snap-lock engagement and enables the floor panel 126 to be separated in two thinner sections. In one alternative embodiment, the floor panel 126 and the wall panel 165 may be jointly post-stressed so that the assembled panels 165, 126 in the ultimate structure have strengths for supporting live loads which greatly exceed the dead load strength of the individual panels 165, 126 as fabricated.
In some embodiments, the system 100 may include a divider 109 that provides additional support to the floor panels 126 and wall panels 165, and enables multiple layers of floor panels 126 to be stacked. This may be useful for multi-story buildings. The divider 109 chiefly serves to separate upper and lower floors in the structure. In some embodiments, the divider 109 may have a substantially rectangular cross section, and an elongated disposition. Though other shapes and dimensions may be used for the divider 109, depending on the needs and specifications of the structure. In one embodiment, the divider has a divider conduit 144 that carries wiring 148 and a water line 150 through the length of the divider 109. In one embodiment, a truncated dividers 134 can be used throughout a tall vertical structure to support multiple floor panels 126 and wall panels 165. The truncated divider 134 may have either side truncated to provide additional support to a wall panel 165.
Returning now to the discussion of the floor panel 126 and the wall panel 165, the floor projections and depressions 130, 132; and the wall projections and depressions 122, 124 form frictional snap-lock engagements with each other. The example shown, shows a double-spike wall projection that is adapted to fit into the identical double-spike shape wall recession of an adjacent wall panel 165. The illustration further shows a cut-out from the wall panel 165, which may be used to incorporate a window or door.

The roof truss 152 is further defined by a pair of lateral ends 154a, 154b. Each lateral end 154a, 154b has a roof frictional channel 156a, 156b that is sized and dimensioned to create the frictional snap-lock engagement with other components, such as the wall and floor panels 165, 126. The roof truss 152 also has a plurality of roof apertures 158 extending along the periphery of the pair of lateral ends 154a, 154b. The roof apertures 158 enable passage of the fasteners 126 for securing panels 165, 126 to the roof truss 152.
Turning now to
In one embodiment, the roof base 164 is the upper-most component in the structure. A roof base frictional channel 168 rests adjacently to the roof base 642. In one embodiment, the roof base frictional channel 168 orients upwardly, towards the roof truss 152 and away from the base 101. However, in other embodiments, the roof base 164, and thus the roof base frictional channel 168 may be oriented downwards or sideways. From any of these orientations, the roof base frictional channel 168 can frictionally mate with the roof panel 160 or the wall panel 165, depending on the design of the structure. A roof base frictional channel cover 125 mates with the roof base frictional channel 168 to prevent snow or debris from filling the roof base frictional channel 168.
In some embodiments, a snow roof truss may be configured for carrying snow from the roof panels 160. The slope of the arc on the snow roof truss may be more defined so as to enable the snow to fall off the roof panels 160. Additionally, the roof apertures 158 are not used with the snow roof truss, so as not to provide a cavity for water or snow to accumulate in. Those skilled in the art will recognize the weight of snow can stress the structure. The snow roof truss, thus helps eliminate this problem through the slope of the arc and the negation of roof apertures 158.
In another embodiment, a block roof panel (not shown) forms a second embodiment of the roof panel 160. The block roof panel engages the roof base 101 to form a junction which can further interconnect with additional roof panels 160. The block roof panel comprises a wedge that slopes down and forms a peripheral region of the roof panels 160. A panel block (not shown) sits adjacent to the wedge. The panel block includes a block panel channel that is adapted to from a frictional snap-lock engagement with the panel block from the roof base 101. A plurality of block roof apertures (not shown) enable passage of fasteners 126 for securing the block roof panel to the roof region.

It will be understood that the advantageous frictional engagement between the panel projections 122, 130, 216 and recessions 124, 132, 219 shown incorporated with the wall panel 165, floor panel 126, roof panel 160, stair panel 127, and L-panel 216 may be readily adapted to other modular structures sections such as corner or angle structures and may also be utilized in other than a vertical plane. For example, the panels 165, 126, 160 may be applied in the form of a horizontal ceiling or roof section with the first and second frictional channels 138, 142 and providing adequate structural rigidity to form a self-supporting structures with flexibility.
